PROP NUT NYLOCK BRASS

D.I.M. has a large selection of nuts, keys, and cotter pins in both brass and stainless steel. We recommend the nylock nut over the castle nut. If you have a Nautique with the castle nut and replace it with the nylock it will cover the hole for the cotter pin, but we have yet to hear of anyone losing a prop with the nylock nut (we know several that have lost them using the castle nut).
